imx8mm with 24-Bit RGB TTL Display

dirkbender — Wed, 15 Jan 2025 13:39:54 GMT

Hello NXP Team,

I am looking for a solution to connect a 24 bit RGB display with a resolution of 480x272 and a pixel clock/DCLK of typ. 9 MHz (8-12 MHz) to the MIPI-DSI interface of the imx8mm.

I have 2 questions:

Can you suggest a solution how I can connect the display to the MIPI-DSI interface (bridge/Converter and so on)?
Do you know the minimum pixel clock that a MIPI-DSI interface can provide? Is it even possible to connect such a slow/small display to the MIPI-DSI-Interface?

Many thanks for your support!

Dirk

Hi @dirkbender!

At the moment we don't have any documentation or solution using a small display on iMX Processors.

We have an Application Note using the iMXRT 1170 with a small display using Mipi DSI protocol.
